Kim Kardashian Flies to Minnesota to Visit Kris Humphries

After landing back on U.S. soil Friday following her abbreviated promotional trip to Australia, the newly single star hopped on a plane again overnight Saturday, this time flying to Minnesota to visit Kris Humphries.

"I'm committed to this marriage and everything this covenant represents," a stunned Humphries -- who was photographed without his wedddng ring Thursday -- told Us. "I love my wife and am devastated to learn she filed for divorce. I'm willing to do whatever it takes to make it work."

Though the NBA star, 26, says he was blindsided by his new bride's filing, a Kardashian pal tells the new issue of Us the Keeping Up With the Kardashians star saw red flags before their lavish August 20 nuptials.

"I felt like I was on a fast roller coaster and couldn't get off when now I know I probably should have," Kardashian blogged Tuesday. "I got caught up with the hoopla and the filming of the TV show that when I probably should have ended my relationship, I didn't know how to and didn't want to disappoint a lot of people."

Confirms a Kardashian pal: "She felt like she couldn't turn back. She got in over her head. She made a big mistake and she knows it."
